Some business card printing places online offer business cards for free. This offer is not only misleading to you but a waste of time and money because you are not getting the quality business card that your business deserves.
Likely these business card size looks smaller, feel thinner or flimsy, and then the print quality looks substandard. I know, you probably told yourself this is just a temporary card until next time around. But you have already paid the full rate for the shipping on the cards, so it's not free to you.
After all, a business card is an extended resume of your business or yourself. Give yourself a starting chance from the start not to fail. You should consider business cards done professionally even costs you a little more. It will make a world of difference getting out there in the competitive market.
